The photosensitive Belousov-Zhabotinsky (BZ) reaction was investigated on a circular ring, which was drawn using computer software and then projected on a film soaked with BZ solution using a liquid-crystal projector. Under the initial conditions, a chemical wave propagated with a constant velocity on the black ring under a bright background. When the background was rapidly changed to dark, coexistence of the oscillation on part of the ring and propagation of the chemical wave on the other part was observed. These experimental results are discussed in relation to the nature of the photosensitive BZ reaction and theoretically reproduced based on a reaction-diffusion system using the modified Oregonator model.
在一个圆环上研究了光敏Belousov-Zhabotinsky（BZ）反应，该圆环是使用计算机软件绘制的，然后通过液晶投影仪投射到浸泡在BZ溶液中的薄膜上。在初始条件下，化学波在明亮背景下的黑色圆环上以恒定速度传播。当背景迅速变为黑暗时，观察到圆环一部分上的振荡与另一部分上化学波的传播共存。结合光敏BZ反应的性质对这些实验结果进行了讨论，并基于使用改进的俄勒冈振子模型的反应扩散系统进行了理论再现。
